Abstract

Purpose
To report a case of preretinal pigmentary proliferation on the fovea after scleral buckling for rhegmatogenous retinal detachment.
Case summary
A 49-year-old female visited out clinic complaining of a visual field defect in the right eye for 5 days. The best-corrected visual acuity (BCVA) was 0.8 in her right eye. Fundus examination of the right eye revealed an upper rhegmatogenous retinal detachment without macular involvement and retinal breaks were found at 11 o’clock and 11’ 30” direction. She underwent scleral buckling, subretinal fluid drainage, and cryoretinopexy under general anesthesia. At postoperative day 4, the subretinal fluid was reduced, but the BCVA decreased to 0.2. The fovea was covered with a brownish pigmentary clump and preretinal hyperreflective proliferative tissue was observed on the fovea by optical coherence tomography. Oral steroid was administered and a decrease of pigmentary proliferation was observed at 2 weeks after surgery. At 3 months postoperatively, the pigmentary proliferation had almost disappeared and the BCVA recovered to 0.8.
Conclusions
Pigmentary proliferation on the fovea may be observed in patients treated with scleral buckling for rhegmatogenous retinal detachment, so careful observation is needed to differentiate this process from other proliferative diseases.
